2- OR 3-WAY MOTOR-DRIVEN VALVE KITS
B
WARNING: The installation of a valve kit on the fan coil unit
is mandatory ACQVARIA.
The kit is made up of:
Ū Brass 2- or 3-way valve with 4 connections with built-in by-
pass, maximum operating pressure 16 bar.
Ū Electrothermal actuator with 230 V or 24 V power supply,
ON/OFF (or modulating) function, total opening time 3 min-
utes.
Ū Hydraulic kit with O-ring for connection with the exchanger
and paper gasket for connection with the valve
Ū Brackets for fastening the hydraulic kit on the side of the unit
in order to ensure stability during transport if the valves are
already installed.

AUXILIARY WATER DRIP TRAY FOR COLLECTING CONDENSATE FROM THE CONTROL VALVES
The auxiliary water drip tray is supplied with the base unit to-
gether with two fastening screws.
Its function is to collect the condensate generated by the control
valves and to convey it inside the main condensate drip tray of
the unit. (FIGURE 15, FIGURE 16)
